h= pesudo random function, a and b id 128 bit key.
1. What i understand is a or b and give this as a input to h. That will be output. Is it like that?
2. and i want to know that how can i store value 128 bit and perform OR operation?
s there any help

That is correct but I believe you have misunderstood what the || operator does.
|| is the logical or operator, it's output is true or false, or in integer terms 1 or 0. The inputs are treated as logical inputs which means in C++ 0 = false anything else is true. Then the implements the boolean logic
OR truth table
You could use bitwise |, that performs the boolean or operator on each pair of bits in the 2 variables, i.e. 0xF0 | 0x0F = 0xFF. But the output of | has the same number of bits as its largest input.
If that is pseudo code and a and b are 128 bit numbers then the easiest way to hold then is as an array of smaller integers, say an array of 4 32 bit integers.
